A high-level HTTP / REST services client for Node.
Set up a client and issue a GET request:
var armrest = require('armrest');
var github = armrest.client('http://api.github.com');
github.get({
url: '/orgs/:organization',
params: { organization: 'shutterstock' },
success: function(organization) {
// do something
}
});Install with npm:
$ npm install armrest
The armrest.client() factory takes two forms: send the base URL as a string if that will get you going, or send an object with parameters below for more flexibility.
Base URL, including any or all of the scheme, host, port, and path. This option overrides host, scheme, and port.
The host part of the base URL if base is not specified.
The scheme part of the base URL if base is not specified, either http or https. Defaults to http. Aliased as scheme as well for compatibility.
The port part of the base URL if base is not specified.
Number of milliseconds to wait first for establishing the socket connection and sending the request, and then again for receiving the response.
Optional parameter, an object specifying a contentType, and functions to serialize and deserialize request and response bodies.
Instance of some logger that implements debug(), info(), warn(), and error().
String indicating criticality of messages to log; one of debug, info, warn, or error.
Make an HTTP request to the service, given the parameters below.
The path component of the URL. URLs may have sinatra-style interpolation tokens to be filled in by values from params.
Paramaters to be sent with the request. For HEAD and GET requests these will be sent as query string parameters. For other HTTP methods, parameters will be serialized according to the serialization scheme associated with the client, and sent in the body of the request.
Callback to be executed upon success, with the deserialized response as the first parameter, followed by the full response object.
Callback to be executed upon failure, with the error as the first parameter, followed by the full response object.
Callback to be executed upon completion, whether the request failed or succeeded, with the error as the first parameter, followed by the full response object, and finally the deserialized response.
Additional parameters are passed through to request.
When you're working with a number of services at once, use the following alternate interface to configure clients and get easy access for later use.
A class method to register backend services. Send a name for the service, and options expected by the constructor, as detailed above.
var armrest = require('armrest');
armrest.configure('github', {
base: 'http://api.github.com',
timeout: 5000
});
armrest.configure('metacpan', {
base: 'http://api.metacpan.org',
timeout: 5000
});Later from elsewhere, load in the module and interact with services by name.
var armrest = require('armrest');
armrest.github.get(...);
armrest.metacpan.get(...);This library was developed by David Chester and Zubin Tiku at Shutterstock
